The Knoxians claim that it's IMPOSSIBLE for Knox to have been in the room where the murder took place because in the areas tested there was none of her DNA, no fingerprints, no footprints. So, it's IMPOSSIBLE for her to have been there.
Well no, it's not impossible and the Latko trial is another example. 20 stab wounds... 2 throats slit: yet no DNA, no fingerprints, no footprints where found.
Vibio,
This is an honest line of thought and series of questions for you. I'm hoping we can find some sort of agreement here.
In general, I agree with you that the lack of fingerprints and DNA of Knox and Sollecito at the crime scene does not
prove they were not there. For example, not to venture too far off into hypothetical movie plot lines, but an experienced hitman who really knows what he's doing can probably kill someone and manage to not leave a trace of his involvement most of the time, by wearing certain clothes, gloves, and with a deep knowledge of what needs to be done to minimize leaving evidence. And by killing the person quickly and efficiently so there's zero struggle. So it's not physically impossible to not leave evidence of the killer behind during a murder, it's just really really hard and requires a lot of thought and planning.
I hope you agree there was no clean up afterwards, correct? Because with a cleanup, Guede's DNA, handprint, and shoeprint would have been removed as well. This means that in order for Knox/Sollecito to not leave a trace, they either would have to not have been physically involved in the murder, or they would have had to be extremely meticulous and careful to not leave a trace of themselves behind. And worn gloves.
So you mention they may have been wearing gloves since it was a cold November night. (Side note: the average high temperature in Perugia is actually 62 deg F with a low of 46 deg F in early November. 17C high and 8C low. Not actually that cold and certainly not glove wearing weather for me. Gloves would actually be uncomfortable.) This is purely speculative but I'll give it to you that they had gloves on that night. Do you agree that generally when people arrive to their destination, they will, at the very least, remove their winter gloves and probably their coat as well? It would be incredibly unusual to leave winter gloves on (when the temperature is in the 50's outside, especially) when you get inside.
This means that what actually had to happen for them to not leave a trace of DNA is that they were wearing gloves, kept them on after arriving home before the fatal argument, and have been extremely meticulous and aware of what they were doing during the murder. And they brought a chef's knife over to the apartment for some incredibly strange reason. This means it almost certainly had to be pre-meditated for your gloves wearing (and chef's knife carrying) hypothesis to be correct. And they had to be incredibly good and aware to not leave evidence behind. Like professional hitman level good. If they were this good and thinking this far in advance, why did they invite Rudy to come, who they didn't even know? Wouldn't people who are borderline professional killers think he would seriously screw things up? AND leave a witness? (Why didn't he mention Raffaele and Amanda in his call to his friend?) Have you ever, in your life, heard of a situation where two people who were this ruthless (some would say they would have had to be professional) would recruit a random unknown to help? And why would two borderline professionals choose a kitchen knife, of all things? Why would Raffaele be involved at all, rent money or not?
Do you agree that for this to have any value as a hypothesis whatsoever, that all of the judeges had to be wrong about the motive? This wasn't a random act of violence that got out of control, or a momentary choice for evil, or a marijuana fueled murder rage. It HAD to be premeditated. And if it was premeditated, why randomly recruit Rudy on the way (beforehand, there would be no way to know they'd even see him!), and why a chef's knife of all things?
If they were this careful to not leave any evidence behind, what the heck is with the bra clasp? They had gloves on! There's no way Raffaele could have deposited his DNA. And what of the other two unknown profiles? Do you agree that, even if they had participated in this group murder, that the bra clasp still had to be due to contamination? Either Raf had gloves on or he didn't. If he did, no DNA anywhere (meaning contaminated clasp). If he did not, then DNA everywhere, like Rudy. Which means he either was not there at all, or he was, wore gloves, and the clasp was still contaminated (no evidential value).
This means that we actually have a premeditated murder and all the judges had to be wrong. The scientific explanations of gastric emptying and time of death have to be wrong. The bra clasp had to be contaminated, since we have ruthless killers, borderline professionals, that know how to kill someone and not leave evidence behind. The knife does not make much sense either -- why a chef's knife and why did it not match the bloody imprint at the crime scene? Weird choice for professionals. Why recruit Rudy out of the blue? Weird choice for professionals. Why did they voluntarily talk to police afterwards to help if they were ruthless killers? Weird choice for professionals. Why did Rudy not mention Amanda and Raffaele in his Skype call since it would be clear they were trying to set up him if this far-fetched scenario actually happened? Weird choice for Rudy. Also weird that he would choose to join in a group murder even though he had no problem with Meredith. Raffaele too! No problems with Meredith, yet he wants to randomly kill her?
I hope you see some holes and implausibilities with your theory. Compare this hypothesis to another one: Amanda and Raffaele were at Raffaele's apartment watching Amelie when the murder occurred. This matches the scientific measurement of time of death according to Meredith's last meal and normal gastric emptying. No crazy theories required regarding pre-meditation, professional killers, randomly recruiting Rudy, randomly bringing a chef's knife. None of that. Just Rudy killing Meredith by himself, since she came home while he was trying to rob the cottage. Bra clasp due to contamination (it had to be due to contamination either way as we discussed above) and no crazy chef's knife scenario (all the independent and non-prosecution experts that have looked at the chef's knife evidence say it is unreliable, the LCN result was contamination, and it certainly wasn't used to kill Meredith).
Why do you favor the explanation with all of the implausibilities, after thinking it through? Isn't it much simpler to think Amanda and Raffaele weren't cold blooded hitmen, and Rudy killed Meredith by himself, since that is what actually matches the known facts and evidence?
Honestly curious what your thoughts are on this, and how you deal with the unusual circumstances required to create such a scenario.
